CREAM AND MILK COOLER.

Specification of Letters Patent.

Patented June 23, 1914.

Application filed March 30, 1914. Serial No. 828,256.

To all whom it may concern Be it known that I, BERNAL H. SHARP, a citizen of the United States, residing at WVoodland, in the county of Yolo and State of California, have invented certain new and useful Improvements in Cream and Milk Coolers; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to new and useful improvements in cooling devices and more particularly to a cream and milk cooler and the primary object of the invention is to provide a simple and eflicient device of this character which will thoroughly cool a liquid as the same is passed therethrough.

A further object of the invention resides in providing an improved structure wherein a water or other cooling circulating means is provided therein for thoroughly cooling the liquid at all points over which the latter flows through the device. v

A further object of the invention resides in providing a device which is sanitary in every respect and capable of being thoroughly cleaned with little or no ditliculty, and still another object resides in providing a device which is simple and durable in construction and extremely inexpensive to manufacture.

Vith these and other objects in view, the invention consists in the novel features of construction, combination and arrangement of parts, as will be hereinafter referred to and more particularly pointed out. in the specification and claims.

In the accompanying drawings forming a part of this application: Figure 1 is a side elevation of a device constructed in accordance with my invention; Fig. 2 is an enlarged vertical section through the device; Fig. 3 is a plan view thereof with the top and strainer removed; and Fig. 4 is a horizontal section as seen on line H Fig. 2.

In describing the invention, I shall refer to the drawing in which similar reference characters designate corresponding parts throughout the several views, and in which 1 indicates a hollow body of inverted frustoconical design, the bottom of which termitop 11.

face 3, the inner peripheral edge of which has an upstanding flange 4 formed thereon. Arranged in the upper portion of the body is a hollow disk 5 which is somewhat conical in design and has the peripheral edge thereof provided atregular intervals therearound with tubular projections 6. These tubular projections are engaged with the inner peripheral edge of the upper portion of the body 1 and afford communication between the interior of this hollow disk 5 and the space between the hollow walls of the body. The top wall of this hollow disk 5 is corrugated as indicated at 7 and the inner wall of the hollow body 1 is also corrugated as indicated at 8, the purpose of which will be hereinafter and more particularly set forth. The upper termination of this conical disk 7 is disposed in a plane above the plane of the upper edge of the annular flange 1 on the top 1 and formed at this upper termination is a cup-like member 9. The bottom of this cup-like member has the greater portion thereof projecting above the downward sloping upper surface of the disk 7, as is obvious from the particular construction described and this bottom is perforated as indicated at 10. A frustoconical cover 11 is provided for the device, the same having a depending annular flange 12 thereon, which snugly engages the outer wall of the annular flange 4 on the body 1. The cover 11 is provided with a central opening around which is provided an upstanding collar or flange 13 which snugly fits the upper portion of the cup 9 projecting through the opening in the center of the The aforesaid cup member 9 is adapted to receive the liquid, such as mils and cream, to be passed through the body of the device, and I have provided a strainer for use in connection with this cup member. This strainer comprises an inverted conical member 1 1 which is hollow and has a depending neck portion 15 thereon fitting snugly within the cup member 9. A cloth or other straining material 16 is adapted to be applied over the upper open end of the member 11 and a rim or band 17 applied to the member to secure the cloth in position thereon. This completes the strainer, and itwill be seen that the same may be readily nates in a neck indicated as 2. The walls of i applied to use and held in position on the this frusto-conical body are hollow, and the i top thereof terminates in a flat annular 1 cup member 9.

body 1 by merely applying the same to the of which terminates within the interior of the disk 7 adjacent the center thereof immediately below the bottom of the cup memher 9. This member 19 forms the outlet pipe for the cooling medium and the outer end thereof may lead to any desired point.

In operation, the device, after being set up as shown in the drawings, is applled to a milk can or other similar receptacle, so that the neck 2 of the body 1 fits within the neck of the receptacle. The inlet pipe 18 is then connected with a source of. water sup after permitting the water to flow t rough circulation of cold water is had through this device. The milk, cream, or other liquid to. be cooled is then poured into "the body through the strainer and the liquid Wlll flow regularly through the openings onto the corrugated upper surface of the disk 7.

This liquid flowing over the disk will 'be somewhat retarded in its downward flow over this surface in view of the corrugations and as the water is under constant pressure against the upper wall of this disk in the circulation of the water through the device, it will be seen that the cream, milk or other liquid will be cooled as thesame passes over this disk. From thedisk 7, the liquid drops downwardly onto the corrugated inner'wall of the body 1 and is there also retarded in its downward flow, so as to. be thoroughly cooled by the water flowingthrough the walls of this portion of the device. The flow j of the liquid through the device will be even, in view of the disposition of the openings 10 in the bottom ofthe cup member 9 and the corrugating of thesurfaces of the device, as described and shown, and the liquid will finally empty through the neck 2 into the receptacle. This coolin process fwillbe rapid, and when the liqui empties into the receptacle, the same will be in proper temperature for whatever purpose the same maybe desired.

During the operation of the device, it will be seen that no dust, dirt nor extraneous matter may enter the device in view of its peculiar construction, thus making the same entirely sanitary, and whenever it is desired to clean parts of the device, ready access may be had thereto by the removal of the strainer and cover, as appears obvious.

From the foregoing, it will be seen that I have provided a simple, inexpensive and efficient means for carrying out the objects of the invention, and While I have particularly described the elements best adapted to perform the functions set forth, it is obvious that various changes in form, proportion and in the minor details of construction may be resorted to, within the scope of the appended claims, without departing from the spirit or sacrificing any of the principles of the invention. v

Having thus described my invention,what Iclaimis: Y j
